Dr. Sharon Parish, a professor of medicine with Weill Cornell Medical College, explained on HuffPost Live that while Viagra targets a man's sexual organs, flibanserin works with the chemistry of a woman's brain.

"This is a drug that works essentially in women's brains, and then certainly the brain interacts with all the parts of the body that are involved in the sexual response," she told host Caroline Modaressy-Tehrani. "But Viagra really works on the genitals. That's not what this medication does. It's not causing an increase in blood flow to the specific area responsible for sexual response."

Parish said the real similarity between Viagra and flibanserin has been the reaction by the public, which has considered them both "blockbuster drugs" and "game-changers." Overall, Parish is glad to see flibanserin receiving potential recognition by the FDA.

"This represents a step forward. This medication, from our viewpoint, has a reasonable benefit-risk profile. There are some risks … but there's also been substantial benefits", she said. "And it's no riskier than any [central nervous system] drug that is available from prescription, or even if you walk in and get [it] off the shelf in some pharmacies, like Benadryl or Claritin."
